' 5 Claims.

My invention relates to reflectors, and more particularly to anadjustable reflector which can be utilized in combination with anelectric lamp so that light may be directed into various paths withoutmoving the. lamp. I g

The main objectof my invention is'to provide a reflector assembly whichmay be utilized to direct light in various directions" from a fixedlamp.

Another object of my invention is to provide an adjustable reflector r vStill another Objectofmy invention is to provide a reflector which maybe utilized to direct light in difierent directions without thenecessity of changing reflectors;

Other objects'of my invention will be apparent or will be specificallypointed out in'the description forming a part of this specification, butI donot limit myself to the embodiment of the invention hereindescribed, as various forms may be adopted within the scope of theclaims.

Other objects of my invention may be more fully understood by directreference to the drawing, wherein:

Figure l is a sectional view of the reflector of a preferred embodimentof the reflector of my invention.

Figure 2 is a top plan View of the portion of a retaining member, cutaway to show the adjusting slot. 7

In many cases, show windows and the like are provided with fixed conduitoutlets, terminating in lamp sockets, and if spot-lighting of anyparticular portion of the window is necessary, either special spotlights are necessary or special directive reflectors must be placed oneach lamp. If the scene in the window is changed, lighting requirementschange, and in many instances it is necessary to completely replace thereflector arrangement.

My invention comprises an adjustable reflector which can be leftpermanently on the lamp'o-r socket, and yet be so changed in arrangementthat the light can be reflected from the lamp in any direction desired,within the limits of the adjustability.

Furthermore, there are many modern lamps which burn onlyin one position.Certain of the gas-filled, high intensity lamps must be burned basedow'n; others, base up; and high intensity, mercury arcs, sodium arcsand similar lamps are always used in a fixed, predetermined position. Insuch cases either a multiplicity of reflectors must be utilized whenfixed outlets are provided, or a device provided such as I will describeherein.

Referring directly to the drawing, a lamp sockolonged t a groo ed-t m l;;-;b1. i thi case I have shown the grooved terminal 8 as being aprolongation of the outer retaining member 3. Screws 2 cooperate with agroove 9 in the terminal 8, and if these screws 2 loosely engage thegroove 9, the reflector may be rotated as well as held in position.

The space Ni between the retaining members 3 and 4 is large enough sothat the periphery the retaining members may passthrough it; and Iprefer to elongate this aperture It so that when the reflector i3 iscentrally positioned with respect to the retaining members that theaperture is completely covered by the retaining members. Beads II and i2provide the only bearing of the retaining members on the reflector l3. 7

In assembling the reflector, the inner retaining member 4 is set up andthe reflector portion 13 is placed over it, so that the cylindricalportion 6 of the inner retaining member passes through the aperture I l.The outer retaining member 3 is then slipped over the reflector portion93 and the inner retaining member, so that cylindrical portions 5 and iiare engaged, and the retaining members are then fastened together. Thus,the reflector portion 13 is held between the two retaining members butmay be moved within the limits of the slot M, as indicated by the brokenlines E5 in Figure l. g V

The reflector assemblyrmay then be inserted in the lamp socket, asshown, and the lamp inserted in the reflector through the space enclosedby cylindrical portions 5 and 6. Thereafter, by a combination of turningmovements of the entire assembly with relation to the lamp socket, andby the angular relationship of the shade of the reflector portion to theretaining in order that the cylindrical portions 5 and 6 of into amultiplicity of paths without the necessity of moving the lamp.

In case it is desired to completely lock the reflector in any desiredposition, screws 2 may be tightened to prevent rotational movement, anda reflector lock screw is provided engaging one of the retaining membersand also bearing against the reflector portion I3.

Other means of locking the adjustable portion to the fixed portion willbe apparent to those skilled in the art.

I claim:

1. In combination with a light source, a reflector comprising a pair ofspaced and opposed retaining members having a spherical curvature, a,reflecting member of greater extent than said retaining members having aportion thereof of spherical curvature concentric with the curvature ofsaid retaining members, said portion fitting in the space between saidretaining members and freely movable therein, allof said members havingregistrable apertures therein for entrance of said light source, and theaperturein said reflecting member being elongated whereby saidreflecting member may be moved to direct light at varying angles fromsaid light source.

2. In combination with a light source, a pair of retaining membershaving hollow cylindrical connected portions and spaced sphericalconcentric portions, and a reflecting member having a portion fittingthe space between said retaining members and freely movable therein tovarious relative positions by virtue of having an elonmembers, lightfrom the lamp may be directed relative position.

4. In combination with a light source, a pair of retaining membershaving hollow cylindrical connected portions and spaced sphericalconcentric portions, and a reflecting member having a portion fittingthe space between said retaining members and freely movable therein tovarious relative positions by virtue of having an elongated slot thereinto allow passage of one of said cylindrical portions therethrough, saidslot being totally covered by said retaining members.

5. In combination with a light source, a pair of retaining membershaving hollow cylindrical 1 connected portions and spaced sphericalconcentric portions, a reflecting member having a portion fitting thespace between said retaining members and freely movable therein tovarious relative positions by virtue of having an elongated slot thereinto allow pasage of one of s'aid cylindrical portions therethrough,andbeads on the periphery of said retaining members for contacting saidreflecting portion.
